I am trying to cluster this network. The vertices are tags and the edges depict the co-occurance of these tags. The edge widths show the number of times a tag pair occurs. 'energy' and 'electricity' occur the most together.
I tried using community detection algorithms in R, especially edge.between.community which gives a modularity of 0.35 with this network. fastgreedy.community does not work on a weighted-edge graph. Is there any other algorithm somebody could suggest for this specific case? I am a novice in both graph theory and R.
